mrncvsn BRICK-MACHINE.

The Schedule refs red to in these Letters Patent and making utt 0! the same.

I, Josl.\n S. ELLIOTT, qt Boston, in the State of Massachusetts, have invented certain improvements in Brick-Mzwhines, of .which the following is a speci fication.

Letters Patent have alreadv been granted to me.

for a brick-pres s and improvements therein, dated February 14, 1860, and J one 26, 1866. v

The present invention consists in a further improvement,whereby the bricks make in the machine shall It consists,fnrther,in a new device for operating therarrier; and, fu.rther, in eei'tain details of coin street-ion, hereinafter particularly, set forth.

. In the drawing- Figure 1. is a front elevation of the machine. Figure 2 is a side elevation of the same. Figure 3 is a vertical section.

Figure 4 is a plan, showing parts below the line:va:

' A is the frame, and

'- B, B. B, and B are g respectively, the .bed, we platforms, and the top the machine.

G is an upright shaft, operated by a large cogwheel rigidly attached to it,'the teeth of which mesh with those of a small cog-wheel on the shaft of the driving-wheel. This latter shaft has its bearings in posts upon theplatform B, as shown.

Upon'the shaft 0. are three cams, D, E, and 1-,.all

At the front of the machine is an upright post, G, the top of which forms the bottom of the mold in which the brick is pressed.

H is amovable platform, sliding up and down in ways, a a, in the frame. In the'center it has a hole,

corresponding in shape and size to a horizontal section of the post G. This hole forms four sides of the mold.

The platform H is moved up and down as follows Two bans, h h, are pivoted to its under side, the lower ends of these bars being pivoted to the outer ends of arms e c, on a shaft, J, which presses-loosely and transversely through the lower part of the post G, and has its hearings in the frame.

The shaft J extends thronghthe frame, and to one end, outside of thefmine, is secured a toothed seg- 'ment, K, into which a segment on the-end of a.le ver,

the posit-ion of the platform-H. The groove isso cut that the roller d is near the lower edge of the cylinder for'most of its revolution, and the platform H v is raised to its utmost limit. For a short distance, the;

rollerworks along the upper edge of thecylinder, and 'thepl'atform is thendown. It will be shown hereafter that the platform is up while the blows are given topress the brick.

designed to form a hollow brick.

The top of the core is always on a level with the -top of the movable platform. H, it being connected, at the lower end, to a bar, ghpassiug through the post G, and secured, at either end,-to the vertical bars g g, attached-to the movable platform, as shown. A

' slot is cutin the 'post G, to allow 9 and g to move up and down. When the platfor'm H is raised to its fullest extent, its upper surface, and, consequently, the top of the mold, is on a level with the platform B.

\Vorking back and, forth on the platform B and the platform when raised, is a. carrier, M. The limit of the movement of the carrier is' fiirty-iive-degrees, between the mold and a hopper, secured to the plat-form B, as shown. The arrierhas no bottom, the platforms B and H serving as a bottom whenit is not over the mold. A

The carrier receives its motion as follows:

It is secured to the outer end of an arm, .0, the inner end of which is attached to a sleeve, k, fitting loosely upon the shaft 0.. Thes'leeve It has a shoul-' der, as shown, to give it bearings upon the platform B.

Below the platform B the sleeve is has a projection, I, which is pivoted to two rods, 0 and 0', connecting, in turn, with the levers m m, 'as shown in fig. 4-in dotted lines.

Each of these levers, m and in, is pivoted to the platform B by' a pin, 12 andn', as shown; and each has, upon its lower side, a pin and roller, p and 11',

also, two carriers and two hoppers, the latter be ing both upon the same side of the machine, eachfortyfive degrees from its mold. Both carriers are operated by, the cam ,E, and, while one is over the mold, the

other isu'nderits hopper.

Connecting the two carriers on a level with their tape is a platform, Q, which, moves with thousand the upper 'pnrt'ot the framing."

R is a knife, secured to a projection fromthe earries by a. set-screw, as shown, to shave thebriek after it is plessed',,ao that the-top of the brik. will be even \vith the top -of the mold, thereby eohsingthe bricks to be of uniform size.
